T (LIZ whom it may concern:

Be it known that I, EDWARD H. WOLF, a citizen of the United States, residing at Detroit, county of Wayne, State of Michi an, have invented a certain new and useful 1nprovement in a Hose-Coupler and Valve, of which the following is a specification, reference being had to the accompanying drawings, which form a part of this specification.

My invention has for its object a hosecoupler and valve; and it consists of the combination and arrangement of devices and appliances hereinafter described and claimed, and illustrated in the accompanying drawings, in which- Fi ure 1 is a view in side elevation, illustrating features of my invention. Fig. 2 is: a view in longitudinal section at right angles to Fig. 1. Fig. 3 is a view of portions of the mechanism, showing the coupler in position to be detached. F1 4 is a view in crosssection through the p unger at right an les to the section thereof shown in Fig. 2. ig. 5 illustrates features of my invention as a plied to a fire-hydrant and showing a slight modification in the construction of the coupler. Fig. 6 is a view in longitudinal section through portions of the coupler mechanism, showing another modification. Fig; '7 is an enlarged view in side elevation, illustrating portions of the device shown in Fig. 5. Fig. 8 is a view in section similar to Fig. 6, the cap 2 being omitted.

My invention is designed to provide a hosecoupler and valve for pneumatic tools for water, steam, gas, and oil pipes, for fire-department hose, and analogous purposes, the invention being designed for any and all uses to which it may be found applicable.

As illustrated in Figs. 1, 2, 3, and 7, a. represents a supply-pipeas, for example, a pipe for supplying compressed air to pneumatic tools, although I do not limit myself thereto. This supp y-pipe is shown provided with a valve, as at b, made reciprocatory longitudinally in the adjacent end of the pipe. Upon the end of the supply-pipe there is engaged a valve-casing'c, provided with a seat upon which the valve 6 seats to close communication through said valve-case. Said valve-case is also provided with a seat e at the extremity thereof, upon which may be seated a plunger f. The valve-case 0 may be en aged upon the su ply-pipe a. in any suitab e manner and is ormed with a channel 9 1 through the outer end thereof. The valve b is provided with a hollow stem h, projecting into the channel 9 and reciprocatory therein, the stem h being constructed with suitable openin s, (indicated at i.) Said valve is also prefera ly constructed with a stem j at the opposite end thereof, extending through the diaphragm is, and a spring Z prefera ly 's employed to normally hold the valve 1) upon the seat (1. The valve-casing is also preferably provided with arms or trunnions m m, extending laterally therefrom.

The plun er is provided with a channel p, communica le through the hollow stem h of the valve 5, the plunger being constructed to be attached to any desired implement by means of a channeled connecting-arm q, opening in the channel p. The plunger is carried by a yoke or framework 1", in which it is made reciprocatory, any suitable means being employed to actuate the plum er-as, for example, a hand screw 8, t eaded through said yoke or framework, as indicated at t, and engaged at its inner end with the plunger-in any suitable manner. The plunger may be connected with any desired member, as with a hose-pipe, a pneumatic tool, a water or steam pipe, and the like, as by means of the connecting-arm g. Said framework is also preferably provided at one end thereof with hooked arms a a to engage the corresponding arms upon the valve-case c. It will be obvious that an implement provided with the plunger may be readily attached to the valve-case c, as by hooking the arms a it upon the. arms m m of the valve-casing of the supply-pipe. i

It will be understood that when an implement provided with the plunger is detached from the valve-casing c the plunger will be in an unseated positioni. a, when it is desired to detach an implement provided with the plunger from the supply mechanism the plunger will be first withdrawn from the seat 0, permitting the ready detachment of the frame or yoke r from the supply mechanism.

It will also be readily seen that when it is desired to attach any implement to the sup-' ply mechanism above described the said yoke or framework is hooked upon the arms m m and that to put said implement into working condition the plunger is seated upon the valve-case 0, thereby moving the valve b away from the seat (1, permitting a free passage of the supply through the extremity of valve upon the seat d when the pipea, and the stem h of the valve 1), the air or other sup ly passing thus through the channel and clianneled arm (1 to the unplement to which the plunger is connected. When the Inn or is to be connected with a fire-hose, rei' er that the channeled arm (1 should not orm a right angle with the passage p, but that the channeled arm (1 should extend at an obtuse angle to the body of the plunger, as shown more particularly in Figs. 5, 6, and 7 and 8.

It will readily be seen that my invention may be'applied to a fire-hydrant and to a fire-hose, the fire-hydrant being provided with a channeled arm '0 in a customary manner, except that said arm is provided with the laterally extended arms m m and that the outer end of the channeled arm 0 should be constructed with a seat w for theextremity of the plunger. As applied to a hydrant the valve (shown in Fig. 2) might be omitted, the ordinary controlling-valve of the hydrant being employed in its place. When my'invention is applied to a hydrant, it will obviously only be necessary that the framework or yoke of the plunger be attached to the arms m m on the hydrant and that the plunger be seated upon the seat w of the hydrantarm 1;. Then by opening the ordinary hydrant-valve free connection is effected from the hydrant through the plunger to the firehose, to which the plunger is connected. Where it is desired to attach an implement quickly to a supply-pipe andwithout the loss of air or other supply, I prefer to employ the valve 6 within the valve-case c-as, for example, upon pneumatic tools. It is readily understood that in the ordinary use of pneumatic tools the loss of air has often been great; but

it will be seen that the valve 6 is automatic in;

its operation and that just as soon as the plunger is released from its seat e the valve 12 will seat and close oil the discharge from the supply-pipe. The spring Z is desirable, especially where the supply-pipe extends vertically, to counteract the gravity of the valve. 1

It will be obvious that the supply-pressure upon the valve 6 will automatically seat said the valve is free to move. In order that the supply-pressure may automatically actuate the valve 6, said valve is provided with a shoulder a: to receive the supply-pressure to automatically close the valve. The plunger and its seat 6 should preferably have a ball-joint connection, so that the plunger may seat closely to prevent any escape of the supply atthe union of the plunger upon its seat.

T0 attach my invention to an ordinary fire-hydrant, the attaching-arm of the hydrant should or arms m m. The attaching-arms of the hydrant are usually formed with a threaded nipple, (indicated at y,) which would be faced up to form the valve-seat w. In double hybe tapped to receive steel studs drants or wherever plural attaching-arms are employed I prefer to provide one or more of such arms with a cap .2, having a threaded en a ement u on the nipple, said ca beim priivi ded with a check-valve (indica ted by the numeral 8) and with a seat (indicated by the numeral 9) to receive the adjacent end of the plunger.

y invention for application to double hydrants also contemplates providing the coupler mechanism with an additional spindle 10, threaded throu h a portion of thescrew s, which would in t "s instance be made hollow,. the spindle passing also through the plun er to bear against the check-valve 8. It wi 1 be evident that by such a construction the engine first to arrive and to attach its hose upon anarm of the hydrant could remove the cap from the nipple attach the hose-coupler as above describe the plunger seating upon the valve w to begin operations. The next engine to arrive provided with a coupler like that indicated in Figs. 5, 6, 7, and 8 by attaching the coupler upon the hydrant-arm and seating the plunger upon the seat 9 of the cap could by means of'the spindle 10 open the check-valve 8 and begin operations'by opening the corresponding hydrant-valve without the necessity of first shutting off the hydrant from the engine already in operation.

I would have it understood that I do not limit myself solely to any particular valve in the valve-casing c or to the hydrant-cap 2. It will be obvious that instead of actuating the valve 12 by the seating of the plunger the provision of the coupler mechanism with the spindle 1O enables me to unseat other forms of valves controlling communication from the supply device to the attached implement. By means of the automatic valve 6, however, an implement could be put into working operation more quickly than would be the case were it necessary to actuate a corresponding valve by means of a spindle 10.

The fire department, it is contemplated, would carry the caps 2, which could readily be applied to the threaded nipple 'y by removing the ordinary cap with which hydrants are customarily supplied. So, also, the fire department might carry the form of coupler mechanism shown in Figs. 5-8 to slip onto the hose. The only change, then, being required in the customary hydrants would be to attach the arms m m thereto.

It will be observed that the yoke or frame 1" is constructed toward the hooked end thereof with an inwardly-proj ecting shoulder, (indicated at the numeral 19,) through which the plunger 79 projects. The shoulder 19 serves to guide the plunger, while also the plunger is laterally movable therein. In other words, the. plunger is oscillatory or swiveled in said shoulder. It will be noticed that the engagement of the screw .9 with the IIO plunger is such as to permit the oscillation of the plun er also. I
